Can't install Catalyst driver for Radeon HD 7970 Ghz Edit - Wrong Device_ID?

[Gangxxter]

Hello there!

I've just bought a new graphics card, the Gigabyte Radeon HD 7970 GHz Edition (Link: http://www.newegg.com/Product/Product.aspx?Item=N82E16814125439).

Before I had a Sapphire Radeon HD 4870 Toxic. I uninstalled the old drivers before I installed the new graphics card. But somehow I'm unable to install the new Catalyst driver for the 7970 Ghz Edit now. The display driver doesn't show up in the Catalyst Install Manager. Manually installing the driver doesn't work either, Windows keeps telling me that the latest driver is already installed (the card is listed as "Standard VGA graphics adapter" in the device manager). I'm on Windows 7 64 bit.

After hours of Google searching I came up with nothing useful.

But I have a long-shot guess why I can't install the driver: it seems the Device_ID for my graphics card is wrong! According to AMD graphics cards from the Radeon HD 7900 series have the Device_ID 6798 or 679A. But my card has the Device_ID 6790!

How is this possible? Is my card defunct? Is there a way to change the Device_ID to the correct ID? I know there is a way to edit the driver's inf-files so I can install it for any Device_IDs. But I don't wan to go this way because I would need to edit the inf-files every time I update the driver.

Is the Device_ID really my problem? Or could the root be something totally different?

Thanks in advance for your help!

First of all, Did you get a diver disk with the new Video card.? Remove all Video drivers if you have driver for the new card.. Next before you do anything, Go to C: Program files/and look for left over ATI folders and delete them.. You might want to run a registry cleaner as well.. Then try to install the new drivers..

Thanks for your suggestions, Ghostman 1!

But I have solved the problem for myself already. I randomly changed the position of the BIOS switch on my graphics card (the Radeon 7970 features a Dual-BIOS for overclocking purposes) and now everything works just fine (BIOS switch is in the original position again now). The Device_ID is reported correctly now and I could install the driver without a problem.
Maybe my problem has something to do with the Intel X58 chipset of my motherboard because this guy had exactly the same problem and also uses a motherboard with the Intel X58 chipset.
